WebThe impurities can react with the component materials and condense at electrochemical active sites, affecting their properties and reducing the performance of stacks [1-3]. Such impurities come from gases (fuels, air, and stack components) and they are usually present in very low concentration levels (lower than several ppm in weight). Webimpurities(S.3.2) on the potential impurities of the API . in terms of their origin, fate and nature.
